BECKHOFF LC3100 Bus Coupler Interface Module

Product Overview

The LC3100 (LC3100) is a fieldbus coupler designed to serve as the gateway between a primary fieldbus network and the modular K-bus terminal system. Serving as the foundation for decentralized automation architectures, this module is essential for industries requiring reliable signal aggregation, including power infrastructure, process control, and large-scale manufacturing. By supporting up to 64 bus terminals and providing high-speed data transfer rates up to 12 Mbaud, the LC3100 ensures seamless and real-time communication between I/O arrays and the central controller, effectively reducing system integration complexity and operational downtime.

Technical Configuration

The LC3100 architecture is optimized for high-density I/O configurations, managing up to 64 bytes of both input and output data. It utilizes automatic baud rate detection to streamline commissioning and simplify network configuration. The module supports a maximum K-bus supply current of 500 mA, enabling the attachment of diverse digital and analog terminal combinations. Designed with a compact 21 mm width housing, the unit installs directly alongside standard bus terminals, utilizing the proven spring-loaded terminal connection method to ensure secure electrical contact in high-vibration environments.

FAQs

What is the maximum number of terminals that can be attached to the LC3100?

The coupler supports a maximum of 64 bus terminals per node, allowing for significant flexibility in scaling I/O counts for complex automation tasks.

Does the LC3100 require manual baud rate configuration?

No, the device features automatic detection of data transfer rates up to 12 Mbaud, simplifying the setup process during network integration.

Is there electrical isolation between the power supply and fieldbus?

Yes, the module includes electrical isolation between the power supply and the fieldbus interface to protect against ground loops and noise injection.

Can this module be used in explosive atmospheres?

The LC3100 carries Ex approvals, making it suitable for specific hazardous area installations, provided that all local safety guidelines and installation requirements are strictly followed.

Installation and Operational Guidelines

• Bus Configuration: When assembling the terminal station, ensure the total current draw of the K-bus does not exceed the 500 mA limit provided by the coupler. Use a power feed terminal if the cumulative current requirements of the connected I/O blocks exceed this value.

• Thermal Management: The LC3100 is rated for operation up to 55 deg C. In dense control cabinets, ensure there is sufficient vertical clearance to allow for passive air circulation. Do not install the coupler directly adjacent to high-heat-generating components like power supplies or heavy-duty motor starters.

• Vibration Integrity: Given its conformity to EN 60068-2-6, the module is designed for mechanical robustness. During installation on 35 mm DIN rails, ensure the locking mechanism is fully engaged and that terminal blocks are secured to prevent lateral movement during operational shock cycles.
